BACKGROUND OF THE INVENTION 1. Field of the Invention

The invention relates generally to apparatuses, systems and methods formaking and dispensing liquids and more particularly to apparatuses,systems and methods for making and dispensing drinks and soft servefoods (e.g., soup, yogurt, etc.).

2. Description of the Related Art

There are several apparatuses, systems and methods for making anddispensing drinks available on the market today. However, they haveseveral limitations. For example, some must use ice to chill thebeverages as they are not equipped with refrigeration systems to coolthe beverages and/or keep them at a set or selected temperature. Otherscannot brew hot beverages. Others can't mix beverages. Likewise, otherbeverage dispensers can't dispense both hot and chilled beverage fromsame spout. To accommodate all beverages, users might have to purchasefour, five, six, seven, eight or more dispensers. That can be veryexpensive and also very inconvenient, to, for example, store all ofthose dispensers.

Some require steel kegs that need to be returned for washing andrefilling. Large amounts of dollars are spent with water waste, carbonfootprint and transportation. Because of high transportation costs, itis typically cost prohibitive for a beer brewery to ship draft beer fromone location to around the world. The same can be true for wineriesusing wine steel and/or plastic kegs.

The global beverage industry can have a negative environmental impact.For example, many consumers do not separate materials before puttingthem into a recycling bin, rendering it costly to separate at therecycler. The result is that these materials may possibly beunrecyclable.

Thus, there is a need for new and improved apparatuses, systems andmethods for making and dispensing drinks that solve the problemsdescribed above, by giving the user the versatility, convenience and theefficiency the user needs, while enabling the user to be environmentallyresponsible, by providing a one-size-fits-all, all-in-one beveragedispensing system that is eco-friendly. That way, the user only needsone apparatus to dispense any beverage.

There is also a need for easily recyclable beverage and food packaging,allowing the user to dispose of the package in single-stream recyclingwithout the need to separate materials.

The aspects or the problems and the associated solutions presented inthis section could be or could have been pursued; they are notnecessarily approaches that have been previously conceived or pursued.Therefore, unless otherwise indicated, it should not be assumed that anyof the approaches presented in this section qualify as prior art merelyby virtue of their presence in this section of the application.

BRIEF SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in asimplified form that are further described below in the DetailedDescription. This Summary is not intended to identify key aspects oressential aspects of the claimed subject matter. Moreover, this Summaryis not intended for use as an aid in determining the scope of theclaimed subject matter.

In one exemplary embodiment, a V-friction coupling is provided thatestablishes airtight seal that allows beverage pumps to pump thebeverage or food and that also prevents air contamination or spoilage ofbeverage in the provided beverage container or keg. The air tight sealalso stops beverage spoilage by oxidation or beverage to go flat intaste. Further, it may prolong the life of beverage in some cases, likein the case of wine, beer or soda. Another advantage is that the samebeverage pour spout of the provided dispensers may be operated with hotor chilled, carbonated or non-carbonated beverage.

In another exemplary embodiment, beverage flavor pods are provided,which could be coffee, tea, coco, soda, flavored powder for fruitflavored beverage, and so on, so that the user could use for examplecoffee flavored pod in a spout pour housing to mix with soda forexample. Further, the beverage flavor pods may have a bar code that canbe scanned by the dispenser to retrieve for example pour instructions.The dispenser may have spikes (e.g., four spikes) to pierce the pod,allowing water/beverage to absorb flavor from the pod, and pourresulting beverage in a user's glass.

In another exemplary embodiment, the beverage pour housing of thedispenser can be used with or without the flavored pod. For example, theuser could place a wine keg in a bay chamber of the dispenser, set thetemperature for that chamber at preferred level and dispense wine. Ifuser decides to remove the wine box from that chamber and install a boxof spring water, the user can make and dispense hot beverage or coldbeverages.

In another exemplary embodiment, the beverage heater and the pump arepart of top lift lid of dispenser, such that the beverage pump draws thebeverage from the keg/beverage container and pushes it through theheater. User however can select hot or chilled beverage via dispenser'scontrols or via smart phone app controls. If chilled beverage isselected, the beverage heater is not turned on. If user selects hotbeverage, heater turns on making the beverage hot.

In another exemplary embodiment, a CO2 control valve selector isprovided allowing for carbonation to flow into beverage keg, or stoppingflow of CO2 gas, allowing for the dispensing of a non-carbonatedbeverage, such as milk or wine.

In another exemplary embodiment, each chamber of the dispenser isindependently controlled, so that each chamber can be set to maintaindifferent temperatures.

In another exemplary embodiment, the beverage container is a disposable,one-way container, made of biodegradable materials. Among otheradvantages, this provides the advantage of lower shipping cost due toless weight of packaging.

The above embodiments and advantages, as well as other embodiments andadvantages, will become apparent from the ensuing description andaccompanying drawings.

DETAILED DESCRIPTION

What follows is a description of various aspects, embodiments and/orexamples in which the invention may be practiced. Reference will be madeto the attached drawings, and the information included in the drawingsis part of this detailed description. The aspects, embodiments and/orexamples described herein are presented for exemplification purposes,and not for limitation purposes. It should be understood that structuraland/or logical modifications could be made by someone of ordinary skillsin the art without departing from the scope of the invention. Therefore,the scope of the invention is defined by the accompanying claims andtheir equivalents.

For the following description, it can be assumed that mostcorrespondingly labeled elements across the figures possess the samecharacteristics and are subject to the same structure and function. Ifthere is a difference between correspondingly labeled elements that isnot pointed out, and this difference results in a non-correspondingstructure or function of an element for a particular embodiment, exampleor aspect, then the conflicting description given for that particularembodiment, example or aspect shall govern.

FIG. 1 illustrates a front sectional view of a drink container,according to an aspect. FIG. 2 illustrates a side sectional view of thedrink container from FIG. 1, according to an aspect. It should beunderstood that while the container 10 will be described herein as adrink container, its uses may be expanded to other liquids (e.g.,cooking oil, motor oil), pastes or viscous materials (e.g., liquid soap,ketchup), or soft serve foods (e.g., soups, smoothies, ice cream,yogurt, etc.) to take advantage of its unique features, such as theV-coupling. As shown, the drink container 10 may be a rectangular box orkeg having an exterior surface 23 and an interior surface 24. The drinkcontainer 10 may also be square. The drink container 10 may be made frombiodegradable cardboard or recyclable plastic that is strong enough tomaintain the container's shape. It should be understood that thecontainer 10 and all other components described herein may be made frombiodegradable materials. The drink container 10 may have a spout 12,which, after filling the container with the drink, is preferably airtight sealed by a foil seal 19 and more preferably also using a petcockvalve 102 (see FIG. 29). The valve 102 holds the seal until userinstalls container 10 into the dispenser, as shown, and as it will bedescribed in more details later when referring to FIGS. 29-32. The foilseal 19 may be removed by a user by pulling on the seal tab 20. On theoutside, the spout 12 may have threads 13 corresponding with the threadsof a cap 11, such that to allow a user to fasten the cap 11 onto thespout 12 or to remove it when necessary.

The container 10 further includes a V-shaped female coupling 15 made ofhard plastic for example, which communicates at its upper end with thespout 12 and at its lower end with a beverage well tube 22. As it willbe described in more details later in this disclosure, the V-shape(e.g., funnel shape) female coupling 15 is configured to receive acorresponding V-shape male coupling 15 b (see FIG. 16 for example) toquickly create a friction air tight seal under the influence of a weightload applied to the V-shape male coupling.

A plastic liner bag 14, preferably biodegradable, is also preferablyprovided to receive and hold the drink (e.g., wine) stored in container10. As shown, the plastic liner bag 14 is preferably fasten, using gluefor example, to the interior wall 24 of the container 10 at severalfastening locations 18, including the corners of the container 10.During the removal (e.g., pumping it out by suction) of the liquid/drinkfrom box 10, the liner bag 14 may have the tendency to move away fromthe interior wall 24 of container 10, as shown at 14 a. Thus, withoutthe fastening points 18, the liner bag 14 may clog the well tube 22. Theclogging of the well tube 22 is prevented by the fastening points 18,and as such, the drink is able to flow easily through the well tube 22out of container 10.

As shown, the container 10 may be equipped with a beverage level sensorstrip 17, which, as it will be described in more detail later whenreferring to FIG. 22, may assist a user in knowing the level of beverageremaining in the container 10 during use and/or alert the user toacquire a new/filled container. Furthermore, the container 10 may bealso equipped with a container CO₂ line 21 for use with carbonatedbeverages. The operation and functions of these two features of thecontainer 10 will also be described in more details later in thisdisclosure.

The container 10 may be used as a mini keg ranging in size from, forexample, ½ gallons to 2.5 gallons, or 6 or 10 gallons, or it may be usedas larger kegs. The container 10 may be for example 4 inch wide, 12 inchlong and 8 inch high.

FIGS. 3-5 illustrate top sectional views of the drink container fromFIG. 1, depicting certain aspects, according to several embodiments.FIG. 6 illustrates a top-side perspective view of the drink containerfrom FIG. 1, depicting certain aspects, according to severalembodiments. FIG. 7 illustrates a fixed, non-adjustable corner brace forthe drink container from FIG. 1, according to an aspect. The cornerbrace may also be provided in an adjustable form, and may fit intodifferent sizes of containers. It is known that CO₂ (carbon dioxide) andother gases, such as compressed air are typically stored/packaged incartridges or canister cylinders or the like, so that gas is evenlydistributed on the wall of packaging. This is why cylinder shapes of gascontainers are typically used, to obtain and maintain equal wall PSI.Right angles in gas containers are typically avoided also because, forexample, the gas can be trapped in right angle pockets. Round cornersallow the gas to flow easily out of the container.

Thus, when the container 10 is intended to be used for example forcarbonated drinks, it may be constructed with fixed or adjustableinterior curved corners (see FIGS. 3-7) that are reinforced to hold forexample up to 35 PSI. This creates a cylinder effect inside thecontainer/box/keg 10. Thus, the container 10 may be constructed withright angles on the outside, which may be useful for stacking andtransportation purposes for example, and round corners on the inside toaccommodate the equal distribution of the gas inside. In other words,the inside of the box 10 may be cylinder (see FIG. 3) or oblong (seeFIGS. 4-5) shaped, depending on the configuration of the outer skeletonof the container (square, rectangular, etc).

To reinforce the corners of the container 10 and to obtain the roundcorners desired, plastic 25 and/or corrugated cardboard 26, or acombination thereof, preferably bio-degradable, may be used to fill thecorners as shown in FIGS. 3-4 and/or to construct fixed or adjustablebraces. The fixed or adjustable corner braces may have solid walls madefrom plastic and/or cardboard, sample structures of which are shown inFIG. 5 at 27 and in FIG. 7 at 27 a.

A container may be made with all corners having fixed corner braces 27,27 a, fastened (e.g., by glue) to them, to obtain inside the cylinder oroblong shape needed to protect the right angle interior corners of thecontainer from gas pressure. Thus, for example in FIG. 3, the exteriorsurface 23 of the container has a square shape while the interiorsurface 24 has a cylindrical shape.

Again, the corner braces may also be adjustable to accommodate variouscontainer sizes. To accomplish this, as shown for exemplificationpurposes in FIGS. 5-6, they may be constructed from a plurality of solidwalls 29 made from plastic or cardboard that can slide with the aid ofthe sliding braces 28. The sliding braces 28 also keep the movable walls29 in place after their sliding in or out. The adjustable corner bracesoffer the advantage of being capable of being used in different sizeboxes. Thus, a manufacturer would need only to manufacture a universal,one-size-fits-all adjustable corner brace. It should be observed alsothat container 10 having a rectangular (or square) shape on the outsideand round corners on the inside has the advantage of having moreinterior volume than a container/box/keg that is round inside andoutside (see FIG. 10). Thus, container 10 can carry more beverage than acontainer/box/keg that is round inside and outside. Further, themanufacturing costs are likely lower for container 10 than a containerthat is round inside and outside.

It should be noted that, when beverage or CO2, air, or gas is placedinside bladder 14, because of the interior box rounded cornerconstruction, the plastic liner or bladder 14 takes the shape of aballoon which forms a cylinder like beverage packaging similar to atraditional steel keg, plastic soda or beverage bottle, glass bottle,can, etc. The unique rounded and reinforced corners of the container 10prevent collapse of the container's walls and corners.

At 30 a beverage mixer and at 31 an opening for adding ingredients tothe drink inside container are depicted. Both elements will be describedin detail later in this disclosure.

FIGS. 8-9 illustrate front sectional views of alternative embodiments ofa drink container. The drink container 10 a has the V-shape femalecoupling 15 extending out of the container, above the upper surface 32of the container 10 a. The thread element 13 for fastening cap 11 isprovided as shown outside and around the portion 15 a of the V-shapefemale coupling extending out of the container. This configuration maybe advantageous for, for example, making it easier for the correspondingV-shape male coupling to slide into the V-shape female coupling 15,without the interference of spout 12 (FIG. 1).

The drink container 10 b has a recess 32 b, which has the thread element13 on its vertical surface to enable the receipt and fastening of cap 11b for closing the container 10 b. The cap 11 b may have a concaveportion 11 ba divided by a separator 11 bb to enable a user toscrew/unscrew cap 11 b. As shown, V-shape female coupling 15 extendsupwards only to the bottom of recess 32 b. This configuration may beadvantageous for, for example, maximizing the space inside drinkdispensers' chambers and for easy stacking of the containers duringtransportation or storage. This is facilitated by the fact that, asshown, the upper surface of cap 11 b is even in this configuration withthe upper surface 32 of the container.

It should be understood that the container alternative embodimentsdepicted in FIGS. 8-9 are shown as examples only. Various other similaralternatives may be adopted without departing from the scope of theinvention. What is important is the V-shape (e.g., funnel shape) femalecoupling 15, which is configured to receive a corresponding V-shape malecoupling 15 b (see FIG. 16 for example) to quickly create a friction airtight seal under the influence of a weight load applied to the V-shapemale coupling.

FIG. 10 illustrates top views of alternative embodiments of a drinkcontainer. As illustrated, the drink container may have various sizesand shapes, such as a rectangular (or square) box shape 10, acylindrical shape 10′ and 10″ and other shapes as shown in FIG. 10 forexemplification purposes. A rectangular box may be adopted for examplefor a flat drink, while a container having round corners (e.g., acylindrical container) may be adopted to carry carbonated drinks, toaccommodate the pressurized gas inside as described earlier whenreferring to FIGS. 3-7. To accommodate for the variation in the drinkcontainer's sizes and shapes, while still ensuring proper alignmentbetween the V-shape female coupling 15 of the container and thecorresponding V-shape male coupling 15 b (see FIG. 16 for example) of adrink dispenser, the container may be equipped with a guiding fin 33 ato be received by a guiding slot 33 b associated with the interior wallof the dispenser's chamber which receives the container (see 33 in FIG.13). The guiding mechanism 33 including the guiding fin 33 a and theguiding slot 33 b ensures alignment of the V-shape couplings in adirection (Y), while the central location widthwise of the V-shapefemale coupling 15 in the container 10 ensures alignment in another,perpendicular direction (X). The combined effect is to ensure properalignment between the female and male coupling.

FIG. 11 illustrates a side sectional view of a countertop drinkdispenser, according to several embodiments. FIG. 12 illustrates thecountertop drink dispenser from FIG. 11 in a different state. As shown,dispenser 50 may have a housing 51, a front door 54, a top lid housing53 and a power source 65. Inside the housing 51, dispenser 50 may haveone or more chambers 52 for receiving one or more containers 10 filledwith liquid 75. It should be noted that front door 54 will have to beopen and top lid housing 53 lifted up (see FIG. 12) high enough, suchthat the V-shape male coupling 15 b escapes from the V-shape femalecoupling 15, in order for container 10 to be pushed in or pulled out ofdispenser chamber 52 successfully.

After a container 10 is inserted in chamber 52, front door will need tobe closed, such that for example a door fin 55 attached to the door canhold the front of container 10 in place. Several (one is shown only fordrawing simplicity) adjustable lateral guide fins 69 (similar to thoseof a printer drawer for example) may be provided to ensure thatirrespective of the width of the container 10, the V-shape femalecoupling 15 is aligned widthwise with the V-shape male coupling 15 b, tomake an air tight seal.

The guide fins are adjustable on the sides 69 as well as rear/back 71,to accommodate different sizes of beverage keg boxes or packaging andensure that the V-shape female coupling 15 is aligned widthwise andlengthwise with the V-shape male coupling 15 b, to make an air tightseal. Guide fins also allow cool air to flow easily around beveragebox/keg 10 by holding box/keg 10 away from the walls of chamber 52.

The guide fins 69 may have a pin latch 69 a (see FIG. 20) fitting incorresponding holes 69 b, to allow guide fin adjustment to be locked inplace. Similarly, for lengthwise alignment of the two couplings, guidingapertures 70 a-70 c (see FIG. 11) corresponding with for example thestandardized lengths of container 10 may be provided, to receive guidingpin 71 behind the back of container 10.

It should be noted that a back to front downward slope (e.g., ¼ inchesper each 12 inches) is provided for the floor 74 of chamber 52 (itshould be observed that floor 74 sits higher in the back with respect tobottom 73 of dispenser 50; this ensures that when dispenser 50 sits on ahorizontal surface the desired slope of floor 74 is obtained). Thismeans that, when placed inside chamber 52, container 10 and its floor 72will also be inclined downward from back to front. Thus, the liquid 75will have the tendency to flow toward the well tube 22, thus aiding pump56 to draw all or substantially all liquid 75 from container 10.

A separation between the V-shape female coupling 15 and the V-shape malecoupling 15 b may be observed in FIG. 11 and in other figures of thisdisclosure. It should be understood that the separation is depicted onlyto properly illustrate the individuality of the two V-shape couplings.However, in reality, when the top lid housing 53 is closed as seen inFIG. 11, there is no separation between the V-shape female coupling 15and the V-shape male coupling 15 b. They engage each other to create afriction seal. The force necessary to create the friction seal ispreferably provided by the weight of the top lid housing 53 and of allthe elements (e.g., pump 56) house into it. It should be understood thatthe coefficient of friction between the two couplings and the weightapplied to the V-shape male coupling 15 b by the top lid housing 53 andof all of its elements have to be coordinated with the pressurenecessary to be maintained inside container 10. For example, for thesame coefficient of friction (e.g., plastic on plastic), a greaterweight will be needed for a greater pressure needed inside container 10(e.g. for carbonated drinks).

The dispenser 50 may be equipped with a replaceable CO2 tank 65, which,as shown, may communicate through a CO2 duct 67 with the V-shape malecoupling 15 b and further with the CO2 line 21 of the container 10, whenthe V-shape male coupling 15 b engages the V-shape female coupling 15 tocreate the friction seal described above. Thus, the friction sealbetween the two V-shape couplings also create a friction seal betweenthe CO2 duct 67 and CO2 line 21. The CO2 may be used to carbonate thebeverage 75 inside container 10.

The dispenser 50 may be also equipped with a refrigeration unit 68(including a compressor, and evaporator and a condenser, similar to thatof a refrigerator) for providing cool air inside chamber 52 for keepingthe container 10 and the beverage in it 75 cool. For this purpose, aseal 61 (e.g., rubber seal) may be provided between the top lid housing53 and the chamber 52, so that, upon closure of the top lid housing 53,the cool air does to escape from the chamber(s) 52. It should beunderstood that the entire chamber 52 will also have to be hermeticallybuilt and the door 54 hermetically closed to keep the cool air insidechamber(s) 52. The top lead housing 53 may be lockable with a latch 62b, which can be actuated (e.g., for release purposes) from a button 62a. Similar sealing and locking means (not shown) may be provided for thedoor 54.

The top lid housing 53 may have as shown the V-shape male couplingattached to it, so that the two lift and close together (see FIG. 12).When opening (lifting up) the top lid housing 53, again, the V-shapemale coupling 15 b escapes from the V-shape female coupling 15 of thecontainer 10, so that for example an empty container may be removed by auser from chamber 52 and a new, full one inserted therein. This is aquick process by a user and thus an advantage of this coupling anddispensing system. A user does not need to go through the cumbersome andtime consuming process of for example screwing couplings together.

The top lid housing 53 may be associated with the dispenser housing 51through a hinge 53 a (see FIG. 12), which may facilitate the opening andclosing of the top lid housing 53. A lifting shock 76 may also beprovided to aid the user in lifting the top lid housing 53. It should benoted that the CO2 duct 67 may need to be flexible enough, or a flexiblejoint 67 a may need to be provided, such that to allow the lifting ofthe top lid housing 53.

Referring now to FIG. 11, as shown, the top lid housing 53 may house apump 56, which can draw the liquid 75 from container 10 via well tube 22and further through male coupling's pipe 22 b and then push it towarddrink dispensing/pour spout 57 via spout conduit 22 c. It should benoted that the friction seal between the V-shape couplings 15, 15 b,described earlier, also creates a seal between well tube 22 and pipe 22b.

Before reaching the pour spout 57, the liquid 75 (e.g., water) pumpedout by pump 56 may be forced to pass through a beverage pod 58 (e.g.,coffee or tea pod). This offers a myriad of possibilities to the user.Not only can a user make coffee and tea, but the user can customize anydrink from the container 10 (e.g., lemon juice) with an aroma or flavordesired (e.g., strawberry) by inserting the appropriate flavor pod 58. Apod lid 59 associated with the top lid housing 53 through a hinge 60, sothat it can be open (see dotted line) or closed, may be provided forfacilitating the insertion and removal of the beverage/flavor pod 58.The pod lid 59 may have similar sealing and locking means (not shown toprevent drawing clutter) as those shown (61, 62 a, 62 b) and describedearlier for the top lid housing 53.

The dispenser 50 may have also a power switch 64 and a control panel 63to give the option to the user to make several selections (e.g.,temperature selection, carbonated/non-carbonated drink, etc).

FIG. 13 illustrates a front sectional view of a drink dispenser havingtwo chambers, according to an aspect. A dispenser 50 may have one ormore chambers 52. It should be apparent that a dispenser 50 that hasmore than one chamber 52 may receive a container 10 in each chamber andthus offer more options to a user. For example, a container may containflat cold water, another may contain a carbonated drink, another maycontain a juice, and so on. As stated earlier when referring to FIG. 11,one or more chambers 52 may be filled with cold air 68 a provided by arefrigeration system 68 (FIG. 11) to keep the respective drink at a settemperature or at a temperature selected by a user. For energy savingpurposes, the walls 51 a of the dispenser housing 51 may be thermallyinsulated. And again, as shown in FIG. 13 and as stated earlier whenreferring to FIGS. 11-12, the top lid housing 53 has to be lifted highenough, such that the V-shape male coupling 15 b retreats completelyfrom the V-shape female coupling 15, in order for the container 10 to beremoved from or inserted into chambers 52.

FIG. 14 illustrates a front view of a drink dispenser having twochambers, according to an aspect. FIG. 15 illustrates a top view of adrink dispenser having two chambers, according to an aspect. It shouldbe understood that a dispenser may have one chamber only, or it may havethree, four (see FIG. 24 for example), six or more chambers. It shouldbe noted that preferably each of the two chambers 52 has its door toallow for independent replacement of containers 10 (see FIG. 13). Itshould also be noted that, for example, one spout module 57 a may belarger to accommodate the housing of the flavor/beverage pod 58 andother elements (e.g., heating elements; see 78 in FIG. 20), while theother may be smaller (57 b). Through the spout 57 of the smaller spoutmodule 57 b, with no beverage/flavor pod, the user may get theunmodified drink (e.g., juice) from the respective container andchamber. It should be apparent that other combinations may be adopted,such as when both (or all if more than two), or none of the spoutsmodules are configured to accommodate the housing of a beverage orflavor pod 58, and/or heating. In addition, the spout module(s) 57 a maybe configured to also allow for the option of pouring the drink out ofcontainer 10 without adding flavor and/or heating and/or cooling.

Further, it should be noted that preferably each chamber 52 of dispenser50 has its own flow controls, or other controls described herein 63 a-b,for a user to select for example how much drink to pour, and/ortemperature control and reader/display 63 c-d to display for example thetemperature in each chamber. Lastly, it should be noted that, as shownin FIG. 11, the refrigeration unit 68, CO2 tank 66 and power supply 65are preferably located in the back portion 77 (FIG. 14) of housing 51.

FIGS. 16-19 illustrate sectional views of male-female couplings,according to several embodiments. In FIG. 16 the V-shape female 15 andmale 15 b coupling is depicted as earlier described when referring tothe precedent figures. In FIG. 17 an alternative embodiment is depictedin which a ridge system 34 may be employed to create the seal betweenthe male and female coupling. A ridge 34 a may be present all around theinterior surface of the V-shape female coupling 15, and similarly, ridge34 b may be present all around the exterior surface of the V-shape malecoupling 15 b. When the V-shape male coupling 15 b descends, as earlierdescribed when referring to FIG. 11-12, into the V-shape female coupling15, as shown, ridge 34 b is preferably configured to pass ridge 34 a,such that the two ridges sit next to each other, to create a seal. Itshould be noted also that the two ridges 34 a-b are squeezed between thetwo couplings proportionally with the weight applied to the malecoupling. This is because the V-shape (e.g., funnel) is narrower at thebottom. Thus, in this embodiment as well, the seal is stronger if moreweight is applied to the male coupling 15 b.

In FIG. 18, a channel 35 a may be present all around the interiorsurface of the V-shape female coupling 15, and a ridge 35 b may bepresent all around the exterior surface of the V-shape male coupling 15b. When the V-shape male coupling 15 b descends, as earlier describedwhen referring to FIG. 11-12, into the V-shape female coupling 15, asshown, channel 35 a is preferably configured to receive ridge 35 b, tolock the couplings and create a seal in addition to the seal between theinterior surface of the V-shape female coupling 15 and the exteriorsurface of the V-shape male coupling 15 b. This embodiment may bepreferred when for example the strength of the seal between the twocouplings has to be controlled. The locking aspect of the channel-ridgesystem 35 makes that possible.

FIG. 19 is offered as an example to illustrate that the male-femalefriction coupling described herein may have other shapes, besides theV-shapes (e.g., funnel shape). For example, the male-female frictioncouplings may have a U-shape or bullet shape as shown in FIG. 19. Othershapes may be adopted, such as cylindrical shape, prism shape, and soon. An advantage of the V-shape is that it also aids to guide and centerthe V-shape male coupling 15 b as it enters the V-shape female coupling15. Further, the V-shape coupling lends itself to a tighter seal. Inaddition, when, for example, the male coupling's pipe 22 b has a beveledlower end or is extended with a beveled nose 22 bb (see FIG. 16), it canslide inside well tube 22 creating an even tighter seal, and thusallowing better suction for the pump 56 (see FIG. 11).

FIG. 20 illustrates a side sectional view of a dispenser system having amixer and other features, according to several embodiments. As shown, amix/stir motor 79 may be part of lift lid housing 53 and may be placednext to beverage pump 56 and behind the beverage heater 78. As it is thecase with all the functions and elements of the dispenser 50 describedherein, the mix/stir motor 79 may be controlled via dispenser controls(see for example 63 a in FIG. 14) or a smart phone app communicatingwith a computer 82 of the dispenser 50. Upon its actuation, motor 79spins a shaft 80. Associated with the shaft 80 two or more drive pins 81may be provided. Thus, the motor 79, the shaft 80 and drive pins 81 willrise together with the top/lift lid housing 53 to allow the insertion ofcontainer 10 into chamber 52. Similarly, they will descend when the liftlid housing 53 will be lowered for closing (see FIGS. 11-12), such thatthe drive pins 81 can engage the corresponding apertures 30 e of a topfin bar 30 f, which can rotate inside a recess 30 c at the top ofcontainer 10. It should be noted that other coupling means between driveshaft 80 and fin bar 30 f may be used, such as friction/clutch means.The fin bar 30 f may be attached to a mix/stir shaft 30 a that goes downas shown into the container 10. The mix/stir shaft 30 a may have severalrotating paddle blades 30 b to properly mix/stir beverages, cocktails orsoft serve-food, ice cream, yogurt, soup, smoothie, juice, cocktails andso on. The rotation of the mix/stir shaft 30 a may be eased by the useof bearings 30 d and 30 g. Bearing 30 d will preferably be configured toprovide also the sealing level corresponding to the pressure leveldesired to be maintained in the container 10 (i.e., higher pressure forcarbonated drinks).

As shown, the container 10 may also be equipped with an ingredientaccess 31, which may be closed using an ingredient/screw cap 31 bfastenable with the aid of, for example, threads 31 a.

The screw cap 31 b is preferably air tight preventing beverage fromgoing flat or being spoiled. When screw cap 31 b is opened, there is apossibility that a carbonated beverage could lose some of itscarbonation. This is not a problem. As soon as top lid 53 and frontdoors 54 are closed, a CO2 sensor 86 (FIG. 22) may be provided to readthe carbonation levels in the beverage container 10 an cause computer 82to automatically add CO2 to container 10, via direction valve 85 a (seeFIG. 21), to re-carbonate to the proper level of carbonation for thebeverage type in the respective container 10.

To create a mixed drink (e.g., cocktail, etc), a user may, beforeinserting container 10 into chamber 52, remove ingredient cap 31 b fromtop of box/container 10, which allows user to add ingredients (e.g.,juice, cut up fruit, etc) into the beverage (e.g., spirit, etc) presentinside container 10. Next, the user would fasten ingredient cap 31 b,thus closing ingredient access 31. Next, a user would insert container10 into chamber 52, while lift lid housing 53 is lifted up (see FIG.12).

Next, the user would close the lift lid housing 53, which will causedrive pins 81 to engage the apertures 30 e of the top fin bar 30 f.Next, the user would actuate the motor 80 via dispenser controls (seefor example 63 a in FIG. 14) or a smart phone app as described above.That would cause the stir shaft 30 a and paddles 30 b to spin and thusmix the added ingredient with the beverage inside container 10.

As shown in FIG. 20, the dispenser 50 may be equipped with cup controlssensors 84 a-b that, via for example light beam 84 c, can read if abeverage container/cup/glass 83 is in place for automatic pour when, forexample, user sets dispenser 50 to pour at a certain time, in commercialuse setting or home use. For example, the night before user goes to bed,user may set dispenser 50 via dispenser controls (see for example 63 ain FIG. 14) or a smart phone app to pour coffee and/or chilled orangejuice at 7:00 am. If the glass/container 83 is in place to receive thebeverage, dispenser 50 will pour the beverage at 7:00 am. Further,computer 80 may be configured to notify user via your smartphone app orflashing light on control panel and/or audio signal that beverage isready.

FIG. 21 illustrates a side sectional view of a countertop drinkdispenser having a CO₂ line for the beverage glass, and other features,according to several embodiments. As shown, the CO2 from the CO2 tank 66may be passed through a direction valve 85 a (e.g., a solenoid valve)electrically-actuable for example by computer 82 based on for exampleinstructions received from a user via controls 63 or a scanner 90 of abar code 89 on pod 58 (see FIG. 22). The direction valve 85 a may sendCO2 either to glass/cup 83 via cup CO2 line 85 or to container 10 viacontainer CO2 line 21. This versatility of dispenser 50 is veryimportant. For example, let's say that the container 10 is filled withspring (flat) water, to make coffee, tea or other non-carbonated drinksusing drink/flavor pod 58. If now the user wants a glass 83 ofcarbonated water, user can for example press the appropriate control 63to send CO2 just into the glass of water 83, leaving container 10 withnon-carbonated water.

FIG. 22 illustrates a side sectional view of a countertop drinkdispenser having a CO₂ sensor, and other features, according to severalembodiments. Again, as mentioned earlier when referring to FIG. 20, aCO2 sensor 86 (FIG. 22) may be provided to read the carbonation levelsin the beverage container 10 an cause computer 82 to automatically addCO2 to container 10, via direction valve 85 a (see FIG. 21), tore-carbonate and maintain the proper level of carbonation for thebeverage type in the respective container 10.

The CO2 sensor 86 may be connected to a male CO2 sensor strip 86 b,which may reside as shown inside V-shape male coupling 15 b. During thecoupling of the female and male V-shape couplings 15, 15 b as earlierdescribed herein, the male CO2 sensor strip 86 b is preferablyconfigured to connect with a CO2 sensor strip 86 a, with which container10 may be equipped, if, for example, the beverage 75 inside container 10is a carbonated beverage.

The dispenser 50 may have a smart beverage volume pour flow controlvalve 88 (e.g., a solenoid valve) controlled by computer 82, so that forexample the user can set, from controls 63 or a smartphone app, thevolume of beverage desired to be poured in user's cup 83 (FIG. 21).Dispenser 50 may also have a beverage volume level sensor 87 which maycommunicate with computer 82 to alert the user when for example beveragevolume is low in container 10. The alert may be communicated to user viauser's smart phone app and/or visual and/or audio alert signal on/fromthe front of control panel 63. The beverage volume sensor 88 may beconnected to a male volume sensor strip 87 b which may reside as showninside V-shape male coupling 15 b.

During the coupling of the female and male V-shape couplings as earlierdescribed herein, the male volume sensor strip 87 b is preferablyconfigured to connect with the beverage level sensor strip 17 ofcontainer 10. Again, as stated earlier when referring to FIG. 1, thecontainer 10 may be equipped with a beverage level sensor strip 17,which may assist a user as described above, in knowing the level ofbeverage remaining in the container 10 during use and/or alert the userto acquire a new/filled container.

As shown in FIG. 22, each beverage flavor pod 58 may have a scannablebar code 89. The dispenser 50 may have a bar code scanner 90 that canread the bar code 89 and then communicate the data to the computer 82.The bar code 89 may contain data regarding to, for example, what kind ofbeverage to pour: hot, cold, carbonated, non-carbonated, ounces ofbeverage, and so on. In addition, the bar code may contain data ofinterest to user, such as nutrition data, which computer 82 maycommunicate to user, for example, on a display (see for example 63 c-d,FIG. 14) of the dispenser 50 and/or on user's smart phone.

Preferably, all bay chambers 52 have a floor 74 that can slide out onroller wheels 91 (FIG. 22), similarly to, for example, a kitchen cabinetdrawer. This feature of dispenser 50 allows easier loading of beveragecontainer 10 into chamber 52. For example, top lid 53 may not be able toopen to a 90 degree angle because of various restrictions, such as theupper kitchen cabinets, when dispenser 50 is used on a kitchencountertop. However, as described earlier, top lid 53 will lift/openenough to disconnect the male and female V-shape couplings, 15 b, 15,allowing a beverage box 10 to slide into chamber 52 when front cabinetdoor 54 is open. However, for example, some beverage boxes 10 that areheavy or with for example irregular or odd shapes may need to be toploaded and adjusted into bay chamber guide fins 69, 71 (FIG. 11) toensure proper alignment of the V-shape couplings 15, 15 b. Therefore,preferably, all cabinet floors 74 slide outward of bay chambers 52.

FIG. 23 illustrates a top view of a drink dispenser having two chambers,according to another embodiment. As stated earlier in this disclosure,each dispenser 50 may have one, two or more chambers 52. In thisembodiment two chambers are shown, each having an independent CO2 supplyvia CO2 lines 67 from CO2 tanks 66. As described earlier when referringto FIGS. 21-22, the CO2 supply is controlled via a directional/smartvalve 85 a by computer 82. In this embodiment, as shown, each spouthousing 57 a may accommodate a beverage pod 58. Thus, the dispenser 50provides the versatility the user may need, such as pouring via each ofthe spouts 57 hot or cold, carbonated or non-carbonated beverage, whichpouring user can control from control panel 63 or a smartphone app asdescribed earlier.

FIG. 24 illustrates a top sectional view of a drink dispenser havingfour chambers, according to an aspect. This dispenser can be used as alarger floor model or corner top model. This is an example of adispenser 50 having four chambers 52 and configured to fit a cornerspace, such that pouring can be done from two sides, left and front inthis example. This two-side access may be advantageous in a commercialsetting for example, when the dispenser may be a floor modelaccommodating larger containers/kegs.

FIG. 25 illustrates a front sectional view of a drink dispenser havingfour chambers, according to an aspect. What should be noted here thatthe dispenser 50 may be configured such that to provide the option ofpouring at the same time via two spouts 57 from each beverage container10. Thus, eight glasses could be filled at the same time. Thisarrangement may be advantageous in a commercial setting for example,when a bartender needs to serve several customers at the same time. Thisdispenser can also be used as a larger floor model or as corner topmodel too.

FIG. 26 illustrates the perspective view of a drink container equippedwith a coupling adapter, according to an aspect. The cost of acommercial size container/keg 10 as described herein, versus the cost oftraditional stainless steel kegs is significantly lower. This is becausethe container 10 is preferably made from biodegradable materials and assuch is a one-way keg. There is no need to return the container/keg 10to the drink manufacturer. Further, there is no need to or expense withwashing the keg. The container 10 can simply and safely be discardedafter use. Thus, besides making the container 10 work with the dispenser50 disclosed herein, there may be a need to make container 10 having theV-shape female coupling 15 and all of its other elements disclosedherein work also with traditional keg system tri-clove fitting used inbeer and wine industry today. This is simply because for example someuser would not want to incur the expense associated with the replacementof their existing keg systems. For this purpose, a coupling adapter 97may be provided, which can be configured to adapt to any existing kegsystems, the uniqueness being the adapter's V-friction male coupling 15b, creating a friction seal with the V-friction female coupling 15 ofcontainer 10 as described earlier in this disclosure.

The coupling adapter 97, as shown in FIG. 26 may include a strap 95,made from stainless steel for example, and having hinges 93 on all fourcorners of container 10 and snap closed/open buckles 94 on one of thecorners, to close/lock the strap 95. Preferably, eight hinges 93 totalare provided. As shown, the coupling adapter 97 may include atraditional keg system coupling 92 (tri-clove) on top, so that existingline couplings can fasten into it. The traditional coupling 92communicates preferably with a V-shape male coupling 15 b placedunderneath of strap 95 and secured by it after entering the V-shapefemale coupling 15 of container 10. A plate 96 may also be provided toprovide depth and to reinforce the fastening of the traditional kegcoupling 92 to the adapter strap 95. The corner hinges 93, snapclosed/open buckles 94 and strap 95 create pressure on the undersideV-shape male coupling 15 b to create the friction seal with the V-shapefemale coupling 15 of the container 10.

FIG. 27 illustrates the side sectional view of a spout housing of adrink dispenser, according to an aspect. FIG. 28 illustrates the processof loading the spout housing from FIG. 27 with beverage pods, accordingto an aspect. So far in this disclosure, reference was made to a spouthousing 57 a of dispenser 50 accommodating one beverage or flavor pod 58(see FIG. 15 for example). In FIGS. 27-28 it is illustrated that thespout housing 57 a may be adapted to accommodate two beverage/flavorpods, 58 a, 58 b, preferably in a stacked arrangement as shown.Similarly, it should be understood that spout housing 57 a may beadapted to accommodate three or more pods, stacked similarly as shown inFIGS. 27-28.

To accommodate two pods 58 a-b in a stacking arrangement as shown, thespout housing 57 a has to have the appropriate height. Further, the podlid 59 preferably have two protrusions 98, such that, upon closure ofpod lid 59, the two protrusions 98 push down onto the flange 100 alocated at the top of a preferably perforated basket 100. The pod lid 59may be locked into the spout housing frame 101 via a latch 59 a. At itsbottom, the basket 100 preferably has two double spikes 99 b that canpierce the upper pod 58 b and the lower pod 58 a. As shown the twodouble spikes 99 b have an upper end extending into the basket 100 and alower end extending away from the bottom of basket 100.

Thus, to use two pods, a user may first place the lower beverage/flavorpod 58 a into the spout housing 57 a and on top of lower spikes 99 alocated at the bottom of spout housing 57 a and oriented upwards asshown. The sharpness of the lower spikes 99 a may be such that toprevent the piercing of the bottom of lower pod 58 a yet. Next, the usermay place the upper beverage/flavor pod 58 b into the basket 100. Next,the basket 100 with upper pod 58 b may be lowered on top of lower pod 58a. The sharpness of the double spikes 99 b may be such that to preventthe piercing of the top of lower pod 58 a and bottom of upper pod 58 byet.

Next, user can push down to close and lock pod lid 59. This will causeupper spikes 99 c attached to the pod lid 59 to pierce the top of upperpod 58 b and upper portion of double spikes 99 b to pierce the bottom ofupper pod 58 b. Further, this will cause the protrusions 98 to push ontoflange 100 a of basket 100, and thus, to push basket 100 downward,causing the lower portion of double spikes 99 b to pierce the top oflower pod 58 a, and, because the basket 100 will push the lower pod 58 adownward, causing the lower spikes 99 a to pierce the bottom of lowerpod 58 a. Thus, now the beverage from spout conduit 22 c may flowthrough upper beverage/flavor pod 58 b and then through lowerbeverage/flavor pod 58 a, before reaching user's cup 83 via spout 57.

To facilitate the flow, basket 100 has preferably a square shape (incross-section), while the pods are preferably of round shape. This wouldallow more space at the corners of the basket 100 for the beverage toflow. In addition, as shown, to also facilitate the flow, the basketwall and bottom may be perforated and the bottom of basket 100 may alsohave a flow opening 100 b.

Now, because of the two-pod configuration, the user can add to theexisting beverage (e.g., water, juice, beer, wine, spirit, etc) in thecontainer 10 any two flavors or beverages users want (e.g., tea, coffee,soft drink (e.g., Pepsi™, Coke™), cherry flavor, etc) to create theirown concoction.

It should be understood that when the spout housing 57 a is configuredto accommodate only one beverage/flavor pod 58 a, the height of thespout housing 57 a is smaller, such that the upper spikes 99 c can reachthe top of pod 58 a upon closure of pod lid 59.

FIG. 29 illustrates a side sectional view of a drink container duringfilling at factory, according to an aspect. It is well known thatcertain drinks such as wine are sensitive to air. For example, the tasteof the drink may be negatively affected if air is allowed to mix withthe drink. Further, air may contain chemical and/or biological elementsthat may contaminate the drink inside container 10. To prevent this,container 10 may be equipped with means that can be selectively engagedto prevent the air from entering container 10 and spoil the drink insideit. For example, container 10 may be equipped with a valve (e.g., apetcock valve) 102, which can close and open the well tube 22 ofcontainer 10.

As shown for exemplification purposes, if this approach is adopted, thewell tube 22 may be extended above the upper surface 23 of container 10,to accommodate a placement of the valve 102 such that it can be easilyaccessed by a user for example. Thus, when container 10 is to be filledat the factory, lever 102 a of valve 102 may be moved up for example, toopen the valve 102, and thus well tube 22 (see valve opening 102 b beingaligned with well tube 22), such that liquid/beverage can be inserted incontainer 10 by factory equipment 103. It should be noted thatpreferably, in order to prevent air from entering container 10, valve102 should be opened after the air tight friction seal is achievedbetween the V-shape female coupling 15 of container 10 and the V-shapemale coupling 15 b (similar to that of dispenser 50) with which thefactory equipment 103 is preferably equipped.

It should be understood that valve 102, at the factory or when in thedispenser, may be opened or closed manually by a user, automaticallythrough a mechanical leverage system (not shown), or, if the valve 102is a solenoid valve, it could be actuated electrically (e.g., automaticcommand by computer 82).

It should be noted that all the other elements and functions of thecontainer 10 disclosed herein remain otherwise the same if notconflicting with the modification(s) depicted in FIGS. 29-32 (raisedwell tube and coupling; valve on well tube). It should be further notedthat all the elements and functions of dispenser 50 disclosed hereinremain otherwise the same, with the exception of slight modificationsthat would be apparent to one of ordinary skills in the art, that may beneeded to accommodate the raised well tube and valve and/or the presenceof a valve.

FIG. 30 illustrates a side sectional view of the drink container fromFIG. 29 ready for storage and/or shipping, according to an aspect. Aftercontainer 10 is filled at the factory, valve 102 is preferably closed,by for example turning lever 102 a down (see FIG. 30), such that toprevent air from entering via well tube 22 into container 10. Next,factory V-shape male coupling 15 b is disconnected. Next, container 10is preferably sealed with foil seal 19 (see FIGS. 1-2) and with cap 11,fastenable using threads 13 for example. The filled container 10 can nowbe shipped and/or stored.

FIG. 31 illustrates a side sectional view of the drink container fromFIG. 30 placed in a dispenser, according to an aspect. When the filledcontainer 10 arrives at the user, foil seal 19 (see FIGS. 1-2) and cap11 may be removed and container 10 may be placed in the chamber 52 of adispenser 50 as earlier described herein, while the valve 102 is stillclosed (see FIG. 31).

As described, the dispenser 50 (see FIG. 11 for example) preferably hasa corresponding V-shape male coupling 15 b, associated preferably withthe top lid housing 53 of dispenser 50. After the airtight seal betweenthe V-shape female coupling 15 and V-shape male coupling 15 b isestablished as earlier described, valve 102 may be opened (see FIG. 32)by for example turning lever 102 a upward as shown. The opening 102 b ofvalve 102 is again aligned with the well tube 22 and thus pump 56 candraw the beverage from container 10 and pour it into user's glass 83(see FIG. 20 for example).

It should be noted that this is a complete closed loop process, from thebeverage factory to user, preventing air from spoiling or contaminatingthe beverage inside container 10. Again, FIG. 32 illustrates a sidesectional view of the drink container from FIG. 31 in a different state(i.e., valve 102 open), according to an aspect.

FIG. 33 illustrates a side sectional view of a drink container, readyfor shipping or storage, according to another embodiment. As shown thedrink container 10, may be adapted to be used for example for a picnicor a pool party, without the need of using a dispenser 50 describedearlier in this disclosure. To that end, it should be noted thatcontainer 10 may have two bags inside, 14 and 103. Liner bag 14 wasdescribed earlier when referring for example to FIGS. 1-2. The inner bag103 is sealed at the top as shown to a shortened well tube 22 and it isthe bag that holds the beverage 75.

Container 10 may be equipped also with an air valve 104 (e.g., a typicalbicycle air valve), which may be used to pump air in the space 109between the liner bag 14 and inner bag 103, and thus force out thebeverage 75 inside the inner bag 103. Any commonly available air pump(e.g., hand air pump, tire pump or compressor, etc) may be used toconnect to air valve 104 and pump air in space 109. It should beunderstood that if container 10 is hermetically built, such as toprevent the escape of the air from its inside, liner bag 14 may beeliminated in this embodiment. It should be noted that well valve 102 isclosed at this time, to prevent air from entering inside inner bag 103and thus prevent spoilage or contamination of beverage 75, as earlierdescribed when referring to FIG. 29-32.

FIG. 34 illustrates a side sectional view of the drink container fromFIG. 33, in use, according to an aspect. Again, container 10 asdescribed when referring to FIG. 33 is configured to be used without adispenser 50. This may be very useful for example for limited budgetparties, such as family picnics or pool parties, student parties, and soon. As shown in FIG. 34, when a user wishes to use container 10, usermay first remove cap 11 (FIG. 33) and replace it with the picniccoupling 105. As shown, the picnic friction coupling 105 may include amale coupling's pipe 22 b, a V-shape male coupling 15 b and a picnic cap11 b.

The picnic friction coupling 105 may be fastened to the container 10 bysimply screwing picnic cap 11 b onto the threads 13. It should be notedthat an air tight seal is created between V-shape male coupling 15 b ofthe picnic coupling 105 and the V-shape female coupling 15 of thecontainer 10, as earlier described in this disclosure. Next, the usermay connect one end of a hose 107, using joint 106, to the upper end ofmale coupling's pipe 22 b. The other end of hose 107, as shown, may havea beverage valve 108 associated with it. The beverage valve 108, mayhave a gate 108 c, which may be lifted to allow beverage flow to picnicbeverage spout 109, by pressing down a lever 108 a, which is loaded witha spring 108 b, to cause the lever 108 a to return upon its release, andclose the gate 108 c.

Next, the user may open well valve 102, such that well valve opening 102a is aligned with the male coupling's pipe 22 b. It should be noted thatbecause of the previously established air tight seal between the V-shapecouplings 15 and 15 b, air will be prevented from entering inner bag 103and beverage 75.

Next, the user may connect an air pump (shown as 120 in FIG. 38) to airvalve 104, and use the pump to push air in the space 109, between theinner bag 103 and liner bag 14. The pumped air in the space 109 willpress against inner beverage bag 103, propelling beverage 75 outward viamale coupling's pipe 22 b and hose 107. Beverage can now be poured viapicnic spout 109 by simply pressing down lever 108 a of beverage valve108.

It should be understood that the order of the above steps is just anexample. The user may for example pump the air inside container 10 athome, and then, when at the picnic site, open well valve 102 and pourthe beverage by opening picnic valve 108.

It should be understood that picnic container 10 can be reusable,disposable and/or recyclable. Same may be true for the picnic frictioncoupling 105, hose 107 and/or picnic valve 108.

It should be noted that while this disclosure emphasized the use of thedescribed systems and methods for dispensing drinks, similarly, they canbe used for dispensing other liquids (e.g., liquid soap, soft servefoods, ice cream, yogurt, etc.).

The beverage container 10 disclosed herein can be made from cardboard,plastic, glass, metal or any combination of these or other suitablematerials.

User may enter type of beverage and/or use by expiration date, viacontrol panel or smart phone app, when installing new beverage box andpackaging. Dispenser's computer 82 may then automatically calculateexpiration date taking into account longer life of beverage because ofairtight male and female V-friction coupling and/or not taking thebeverage container in and out as it is the case when using a standardrefrigerator. For example, open soda, wine, beer, will go flat after ashort period when using a standard refrigerator. As another example,milk going in and out of refrigerator shortens beverage life. Theairtight system and process disclosed herein extends the life ofbeverage.

It should be noted that the dispenser controls 63 of each chamber 52 orthe smart phone app described earlier in this disclosure, which may beused for example to remotely set beverage pour, may be configured tocontrol a variety of functions and display a variety of data, such as:beverage chamber temperature control setting (each chamber may beindividually controlled for temperature); chamber temperature readingdisplay; beverage selection (e.g., carbonated or non-carbonated; hot asin coffee or cold as in soda); beverage low volume alarm; beverageexpiration date controls alarm; beverage container in place ready topour (communicates to users that a mug, glass, cup, travel container orpitcher is in place to receive beverage; if no beverage container is inplace dispenser will not dispense selected beverage); two stationcontrol valve and sensor for flow direction to pour spout (this multiplepour control allows one beverage keg box, packaging to supply beverageto move than one pour spout); auto select beverage, hot or cold (a hotbeverage selection, causes pump to circulates beverage from chamberthrough element heating coils to heat beverage before entering cabinethousing where flavor pods are positioned, allowing flavored beverages,such as coffee, tea, hot cocoa, or even hot milk to be poured); CO2 PSIpressure control selector switch and gauge system showing PSI; childlock out control preventing children from pouring soda or energy drinkswithout parent permission; displaying what type of beverage is in whichchamber after user enters beverage type (e.g., beer, lite beer, redwine, white wine, milk, soda, diet soda, water, coconut water, energydrink, orange juice, and so on); in a commercial setting, dispenser (seeFIG. 25) may be set up to self-serve driver's license reading for ageappropriate alcohol requirements (reader determines if self-servecustomer is old enough to purchase alcohol; it can also acceptself-serve customers credit card or beverage ticket for automatedpayment for beverage to relieve long beverage line at big event venuessuch as sporting events and concerts).

FIGS. 35A-35D illustrate side sectional views of four examples of adrink container 10, according to an aspect. As shown, the drinkcontainer 10 may be a rectangular box or keg. The keg 10 may beconstructed of plant-based bio-plastic, bio-cardboard, regular plastic,regular cardboard, or steel. The keg 10 is preferably constructed frombiodegradable materials.

FIG. 35A illustrates a keg 10 that may be used for water or anotherbeverage that does not need to be mixed or stirred. A well tube 22 mayextend down into the keg 10, through which liquids or soft serve foodsmay be drawn.

FIG. 35B illustrates a keg 10 with a mix/stir shaft 30 a that may beused for beverages that may need to be stirred or mixed, such as, forexample, juices, energy drinks, chocolate milk, pre-mixed cocktails,coffee, tea, lemonade, and so on. The mix/stir shaft 30 a may extenddown as shown into the container 10. The mix/stir shaft 30 a may haveseveral rotating paddle blades 30 b to properly mix/stir beverages,cocktails or soft serve-food, ice cream, yogurt, soup, stews, pasta,rice and meat, poultry, fish, smoothies, juice, cocktails and so on.

FIG. 35C illustrates a keg 10 that may be used for soft serve foods suchas, for example, ice cream, yogurt, soups, stews, macaroni and cheese,and so on. The keg 10 may include a mix/stir shaft 30 a having paddleblades 30 b and may have an auger conveyor/lifting silo 110, which maybe capable of vertical or horizontal ushering of the food or liquid. Thekeg 10 may also have a sloped floor 125, which may assist in guiding thesoft serve foods to the auger conveyor/lifting silo 110. The keg 10 mayalso include horizontal ushering 125-a to move soft serve food.

FIG. 35D illustrates a keg 10 that may be used for dispensing tap water,or water found at, for example, a camping site. The keg 10 may be fittedwith a biodegradable water filter 111, such that water is poured intothe keg 10 through the filter 111 and the keg 10 may then be closed witha removable cap 11. After water is poured into the keg 10 through thefilter 111, it may be drawn out through the well tube 22. The well tube22 may also include a second water filter (not shown), for addedprotection. The biodegradable water filter 111 may be single use ormultiple use. An advantage of the single use filter may be that usingthe same water filter for an extended period of time may be unhealthy,and may collect impurities. The keg 10 may be constructed in sizesranging from ½ gallon or smaller to 10 gallons or larger.

It should be understood that a keg may include a plurality of chambers,each of which may include the components shown in FIGS. 35A-35D. Eachchamber may house a different type of liquid or food, and may includevarious components for mixing, for example. As an example, a keg mayinclude two or four chambers with a beverage in some and soft serve foodin the other chambers. The various chambers may be used with adispenser, which may include a bar code reader, a microphone for voicecommands, or a user ID scanner, for example. The various chambers mayinclude barriers in between, such that heat or cold are shielded fromother nearby chambers.

FIGS. 36A-36B illustrate side views of a drink container or keg with ascrew-on cap, two couplings, two safety valves, and well tube 22,according to an aspect. The keg 10 may include a pressure relief safetyvalve 133, and another pressure relief safety valve 113-a at the pourspouts 57. The keg 10 may also include an air valve 104. Again, the usermay connect one end of a hose 107, using joint 106, to the upper end ofmale coupling's pipe 22 b. The other end of hose 107, as shown, may havea beverage valve 108 associated with it. The keg may include two pourspouts 57, a pour spout at the top, and another pour spout at thebottom.

FIG. 36C illustrates a side view of a drink container or keg 10 with ascrew-on cap 11 and female cylindrical coupling 215, according to anaspect. The cylindrical coupling 215 may be a U-shaped channel as shown,which may accommodate a bull-nose male coupling (not shown), forexample. The channel may have a concave bottom, or may have a flathorizontal level bottom, as shown. The keg may also include an air valve104 for, again, pumping air in the space 109 between the liner bag 14and inner bag 103, and thus force out the beverage 75 inside the innerbag 103.

FIG. 36D illustrates a side view of a drink container or keg 10 with aV-shape male friction coupling 15-b that may be a part of a factoryfilling line, according to an aspect. The V-shape male friction couplingmay be used with a cylindrical female coupling 215. The lid and couplingmay also be a male cylindrical coupling 215-b which may correspond to afemale cylindrical coupling 215 as shown in FIG. 36C, according to anaspect.

FIG. 36E illustrates a perspective view of a drink container or keg 10showing examples of where a V-shaped or cylindrical coupling may beplaced, according to an aspect. The female coupling for a receiving acorresponding male coupling, shown by 215-a, may be either V-shaped orcylindrical. The keg 10 may also include handles 132. The keg 10 mayalso include at least a corner brace 132-a (with some portions not shownfor visual clarity, shown in more detail in FIG. 36F), which may beprovided at one corner of the keg 10 or more than one corner.

FIG. 36F illustrates a detailed perspective view of the corner brace132-a of FIG. 36E. The corner brace 132-a may include sliding portions132-b for extending or adjusting the size of the brace such that thecorner brace may be used in different sizes or models of kegs, forexample. The sliding portions 132-b may be locked into place with a pin132-c, for example, or any other suitable means. The corner brace mayalso include teeth 132-d (not shown in all areas for visual clarity) forthe sliding portions 132-b to grip with the main corner brace 132-a.

FIGS. 37A-37K show sectional top perspective views of examples of abioplastic pressure relief safety valve 113, preferably biodegradable,which may be manually adjusted for different PSI, and may be reset ifactivated to release pressure inside of the keg, according to an aspect.The resetting may be automatic, and the pressure relief safety valve may“self-reset.” As an example, the weight of the top of the safety valvemay cause the top portion to be pushed downwards when not forced upwardsby pressure inside of the keg. As another example, an actuator withinthe keg may reset the safety valve cap, and may do so when a sensordetects that the safety valve has been used to relieve pressure. Asanother example, the resetting may be performed manually by the user.Upon resetting, the safety valve may be configured to maintain the samePSI as previously, or a different PSI. More than one safety valve may beused in one container. For example, one safety valve may be used torelease excess pressure in the beverage cavity of the keg 10 where thebeverage is stored, and a second safety valve may be in an air cavitywhere air pressure is used to self-propel the beverage from the keg 10.The pressure relief safety valve 113 may be constructed in a variety ofways, and preferably constructed from the same material as the keg. Anadvantage may be that this aids in the ease of recycling, andsingle-stream regenerative recycling may be possible with the componentsof the safety valve, including springs and rubber bands, constructedentirely of the same bio-plastic material, for example. The user mayrecycle the entire container without separation of its parts.

FIGS. 37A-37B illustrate side views of a pressure relief safety valve113-a in a closed sealed position and activated open position,respectively, according to an aspect. High pressure may force the valveopen, by raising the lid 114 into the activated open position of FIG.36B to release the excess high pressure. The lid 114 may include springhinges 115 that may hold arms 116 against the side of the valve 113-a.The arms 116 may clip onto a padded or ridged area 117 attached to theside of the valve 113-a. The inside of the valve 113-a housing may haveridges 118, which may create a friction hold for the lid 114, which mayextend down into the housing by a shaft 114-a. The lid 114 may also havehooks 114-b which may hook into the ridges 118, holding the lid 114 inplace. This may also help to hold the lid 114 against seal rings 119. Asan example, either the hooks 114-b or the ridges 118 may be flexible,such that the hooks 114-b may move upwards or downwards past the ridges118 as needed.

FIGS. 37C-37D illustrate a side view in a closed state and front view inan open state, respectively, of a pressure relief safety valve 113-b,according to an aspect. The keg may include two pressure relief safetyvalves, such that one may be for releasing air and another may be forreleasing gas resulting from fermentation. As an example, a pressurerelief safety valve 113-b may include a long hook or rod 114-c that mayhook into the ridges 118, holding the lid 114 in place. Again, as thelong hook 114-c or the ridges 118 may be flexible, such that the longhook 114-c may move upwards or downwards past the ridges 118 as needed.

FIG. 37E-37F illustrate a side view and a front view, respectively, ofanother example of a pressure relief safety valve 113-c, according to anaspect. The pressure relief safety valve 113-c may include ridges 118along the sides of the walls, which may catch a rod to keep the safetyrelief valve open or closed in a desired open or closed position.

FIG. 37G illustrates a front view of another example of a pressurerelief safety valve 113-d, according to an aspect. The hooks 114-c ofthe safety valve may be raised and lowered by springs 114-d.

FIG. 38 illustrates a side sectional view of a keg 10 that mayself-propel beverages or foods 75 without the need for electricity,according to an aspect. An advantage may be that additional expense forelectricity may not be needed, and the keg may thus be portable. The kegmay also reduce the carbon footprint by not using electricity or gas topropel a beverage. A user may pump an air pump handle 120, which mayforce air into the keg in the space 109, between the inner bag 103 (also“beverage bag”) and liner bag 14. The pumped air in the space 109 willpress against inner beverage bag 103, propelling beverage 75 outward viawell tube 22. The air bag may keep air in the air bladder chamber, whichmay create air pressure against the beverage bag. As air pressure isincreased, the pressure may push the beverage 75 up through theV-friction coupling 15. The air pump 120 may be held in place by straps122, and may be built in to the keg and may be a part of the keg. Theair pump 120 may have an intake hole 121 which provides the air neededfor the air pump plunger action to fill the air bag inside of the keg.An air exit hole 123 and air pump gate flap 124 may restrict air fromleaking out of the air bladder, which may maintain pressure against thebeverage bag. This may aid in strong propulsion of the beverage. One-wayair flow may also be provided by the air gate flap 124 as shown, or by aone-way air valve, or ball valve air lock, for example. As an example,the keg 10 may have an outer liner bag 14, or the outer shell may berigid. The outer liner bag 14 may create a hermetically sealed chamberand may be connected to the keg's inner walls by glue or any othersuitable means, and the keg may also include safety pressure reliefvalves 113. As an example, the keg may include a plastic, solidcontainer instead of an outer liner bag, with a beverage bag 103 insideof it. As the beverage is emptied from the beverage bag 103, thebeverage bag 103 will be reduced in volume and may slide up the wall ofthe keg, forcing the beverage towards the opening in the femaleV-friction coupling 15, or cylindrical coupling (as shown in FIG. 49A as215). Again, the plastic liner bag 14 is preferably fastened, using gluefor example, to the interior wall (as shown as 24 in FIG. 2) of thecontainer 10 at several fastening locations 18, including the corners ofthe container 10. An air nipple or air valve 104 may be used in order toautomatically keep air pressure in the air chamber at a constantautomated pressure. The air nipple or valve 104 may be used in a kegwith or without an air pump 120. It should be understood that the kegmay be used with or without an electric air compressor, or with orwithout a hand air pump.

FIGS. 39A-39C illustrate various examples of a keg 10 that mayself-propel liquids or soft-serve foods with or without an externalenergy source, according to an aspect. The keg 10 may include a pourspout opening 57 (not shown in FIG. 39B for clarity), which mayaccommodate a V- or cylindrically-shaped friction coupling (not shownfor clarity). The keg may have a sloped floor 125 directing liquids orfoods to the pour spout opening and an auger conveyer/lifting silo 110.As shown in FIG. 39A, the sloped floor 125 may be in a V-shape such thatthe liquid or food is directed to the center point of the pour spout.The sloped floor 125 may be fixed or may move. As shown in FIG. 39B, theinterior of the keg 10 may be cone-shaped as shown by 125-a to directfood or liquids towards the auger screw conveyor 110. As shown in FIG.39C, the sloped floor may also be raised by a spring 128. To lift andcreate a sloped adjustable floor inside of the keg 10 for gravity flowof liquids or foods, the bottom plate may increase its slope as theliquids or foods are drained from the keg. The lifting pressure may becreated by the rubber bands or springs to lift the bottom plate. Theexamples of kegs shown in FIGS. 39A-39B may need an external energysource to power the auger, and the example of the keg shown in FIG. 39Cmay not need an external energy source.

FIG. 40A illustrates an example of layered board 150 that may be usedfor the construction of a keg 10. The layered board 150 may beconstructed from bio-plastic, wood, cardboard, steel, or any othersuitable materials. The layered board 150 may be used as a liftingpressure plate, and may be used to hold the top plate of the keg 10,coupled together for lifting strength. The layered board 150 (shownwithout layers in FIGS. 40B-40D for clarity) may form the top of the keg10.

FIG. 40B illustrates an example of a keg 10 that may self-propelbeverages or foods using side wall pressure plates 24-a, according to anaspect. The side wall pressure plates 24-a may be bio-plastic or anyother suitable material. The keg 10 may include a V-shaped orcylindrical friction female coupling 215-a for receiving a correspondingmale coupling. The coupling 215-a may include a safety relief valve113-a and may include a petcock valve 102. It should be understood thatall friction couplings may include a safety relief valve 113-a and mayinclude a petcock valve 102. The side-to-side propulsion may be achievedby the side wall pressure plates 24-a pressing against the beverage bag103. To assist the side wall pressure plates 24-a sliding along the topand bottom of the keg 10, the side wall pressure plates 24-a may befitted with, for example wheels 140, or as another example, skis (notshown). The side wall pressure plates 24-a may also be assisted insliding by fitting into guide pins (not shown), or be free floating, asshown. Side-to-side propulsion may also be achieved by springs 151applying pressure to the beverage bag 103, which may be, for example, aplastic bag, or a balloon bladder, which may be similar to a waterballoon. The springs 151 may push between the outer walls of the keg 10and the side wall pressure plates 24-a. A second bio-plastic outer sidewall 24-b (shown on the right side of FIG. 40B only for clarity) may beneeded on the inside of the keg wall to press against the side wallpressure plates 24-a inside of the keg wall.

FIG. 40C illustrates an example of a keg 10 that may self-propelbeverages or foods using a gravity flow sloping floor plate 152 to liftone end of the beverage bag 103 at the bottom of the keg 10, accordingto an aspect. The floor plate 152 may be lifted, such that the elevationmay create a sloping floor to direct the liquid or food in the beveragebag 103 towards the pour spout 57, which may also include a safetyrelief valve 113-a and may include a petcock valve 102. The floor platemay be lifted using elastic bands 139 which may be bio-rubber or anyother suitable material. The elastic bands 139 may be attached toeyehooks 139-a, which may be round as shown, or may any other suitableshape. The elastic bands 139 may, through pressure, lift the slopingfloor plate 152 as the weight of the beverage bag 103 decreases whenbeverage is removed from the container. When the floor plate 152 islifted, the beverage bag 103 may be pressed against a stationary topplate 152-c, to help release the bag's contents.

FIG. 40D illustrates a self-propelling keg 10 having a lifting floorplate 152-a, according to an aspect. The lifting floor plate 152-a maybe positioned at the bottom of the keg 10 as a bottom plate, and may beraised and push the contents of the beverage bag 103 by pressure appliedby elastic bands 139-a, which may be connected to eye hooks 139-a, asdiscussed when referring to FIG. 40C. The eye hooks 139-a may beattached to the top plate 152-c on the other end of the keg, which maybe stationary. The weight of the beverage inside of the beverage bag 103may be lessened as the petcock valve 102 of the coupling 215-a isopened, and thus the lifting floor plate 152-a may be raised. Again,when the lifting floor plate 152-a is raised, the beverage bag 103 maybe pressed against a stationary top plate 152-c, to help release thebag's contents.

FIG. 40E illustrates a self-propelling keg 10 having side walls 24-a,according to an aspect. The keg 10 may contain a bio-plasticbladder-type bag 103 upon which the side walls 24-a may push from twosides, to evenly push liquid or beverage out from the friction coupling215-a, which may be associated with a pour spout for pouring out thecontents of the keg. The two side walls 24-a may be held together byelastic bands 139 hooked into eye hooks 139-a, for example, and be heldin place by the inner bag 103 The side walls 24-a may then squeezetogether as the contents of the inner bag 103 are released and thevolume of the bag 103 decreases. The side walls 24-a may be on skis140-a in order to facilitate sliding across the bottom of the keg 10. Asanother example, wheels 140 (as shown in FIG. 40B) may also be used forthe side walls 24-a.

FIG. 40F illustrates a self-propelling keg 10 having a moveable topplate 152-c at the top and a stationary bottom plate 152-a, and aflexible hose 180, according to an aspect. Again, the keg 10 may includea V-shaped or cylindrical friction female coupling 215-a for receiving acorresponding male coupling. The coupling 215-a may include a safetyrelief valve 113-a (as seen in FIG. 40B) and may include a petcock valve102. Similar to the keg shown in FIG. 40D, the beverage bag 103 may bepressed downwards onto the bottom plate 152-a, by the downward force ofthe top plate 152-c moving downwards. The top plate 152-c and the bottomplate 152-c may be held together by eye hooks 139-a and bands 139 (shownonly in rear of FIG. 40F for visual clarity, and also shown in theexample of FIG. 40G) such that the keg 10 may self-propel the contentsof the bag 103 as it is emptied. As the top plate 152-c pressesdownwards on the bag 103, the contents of the bag may be propelledthrough a flexible hose 180, which may be attached to the bag 103 at ajoint or hole 181. The hose 180 may then connect to a female coupling215-a through which the contents of the bag 103 may be dispensed. Theflexible hose 180 may, as an example, connect to a coupling at the topof the keg 10 with another outer flex hose, which may connect to a gatevalve (as shown in FIG. 40G). As shown as an example, the flexible hose180 may be included inside of the keg 10.

FIG. 40G illustrates another example of a self-propelling keg 10 with aflexible hose 180 connected to a bottom coupling 215-a, according to anaspect. Again, the keg 10 may self-propel by a downward-pressing topplate 152-c, for example, exerting pressure onto a bag 103. The downwardpressure may push a beverage or food out of a coupling petcock valve215-a, which may be located towards the bottom of the keg 10. Thecoupling 215-a may have a flexible hose 180 attached to it, throughwhich a beverage or food may be dispensed as the weight of the bag 103contents are pushed down by gravity and by the downward force of topplate 152-c. With the assistance of the force of gravity, less pressuretension is required on the rubber bands 139. The bands 139 and eyehooks139-a may be provided at one end of the keg 10 or may be provided atmore than one end of the keg 10 (shown only in rear of FIG. 40G forvisual clarity). The end of the hose 180 may be attached to a pour spouthaving a gate valve, which may then dispense a food or beverage into acup 181. As an example, the bag 103 may be capable of holding 10gallons, the weight of which may be approximately 90 pounds withdownward pressure. With downward movement instead of upward, lesstension may be exerted on the bands 139. As shown as an example, theflexible hose 180 may be outside of the keg 10.

The beverage bag 103 of FIGS. 40B-40G may be of an elastic type materialthat may expand. The elasticity may add propulsion force, which may helpto lift or push the beverage towards the pour spout 57 or coupling215-a. The keg 10 may have multiple pour spouts 57 such that the usermay position the keg 10 in different ways. No external energy source maybe needed to propel or dispense a beverage or food from the containerwhen pressure is applied to the beverage bag 103.

It should be understood that any keg 10 may include any combination ofcouplings, pressure relief safety valves, mixing paddles, and any otherfeature described herein.

FIG. 41A illustrates a self-propelling keg 10 having telescoping legs129 and an accordion outer shell 10-a, in a filled state, according toan aspect. A keg having telescoping legs may or may not have anaccordion outer shell 10-a. It should be understood that the keg 10having telescoping legs 129 may also include any of the other featuresdescribed herein, such as, for example, a coupling 215, and elasticbands 139 and eyehooks 139-a. The keg may include a top plate 152-c anda bottom plate 152-d. The plates may squeeze the inner bag 103 that maycontain a liquid or food. As the top plate 152-c and bottom plate 152-dwork together, the inner bag 103 may be squeezed evenly to push all ofthe contents of the inner bag. The telescoping legs 129 may allow forthe keg to be collapsible, to be stored and shipped flat. For example,the outer shell 10-a may be flattened or collapsed by using theaccordion folds, and then the keg may also be folded into a smallershape by folding along seams such as seam 153. The telescoping legs 129may act as stanchion posts, supporting the structure of the keg 10, byconnecting to the top plate and the bottom plate inside of the keg 10.In another example, posts that are fixed in length may be used in placeof the telescoping legs 129. When fully extended, the legs 129 may beused to support the vertical stacking of the keg when it is full ofproducts such as beverages or food. The keg 10 may be constructed of anysuitable material that may be folded or collapsed, and again, mayinclude seams for collapsing the keg 10, such as at 153. The outer shell10-a of the box may expand similarly to an accordion, due to itsaccordion-like folds (shown on two edges of outer shell only forclarity), when the legs telescope and extend. When the legs collapse,the accordion box may compress. Thus, the accordion box and telescopinglegs may assist in the keg taking up less space than a traditional steelor plastic keg. As an example, a keg 10 may be constructed by foldingfull folds of box sides over one another, such that an entire side ofthe keg 10 has two layers of cardboard or any other suitable materialthe keg may be constructed from. Multiple pieces of the adhesive used tosecure the folds may be overlapping with each other for addeddurability.

FIG. 41B illustrate three examples of telescoping legs 129-a-129-c,according to an aspect. The telescoping legs may be constructed in avariety of ways as shown, or in any other suitable design. The legs mayalso be fixed as an alternative to telescoping. The legs may beconstructed from any suitable materials, such as metal, cardboard,bamboo, and so on. The telescoping legs 129-a-129-c may be locked into adesired length by fitting pegs or pins (not shown) that may be pushedinto a hole 129-d. The pegs or pins may be spring-loaded and may snap orlock into place when inserted into a hole 129-d. The legs may beextendable without being telescoping, such as, for example, by havingaccordion folds, or any other suitable means.

FIG. 41C illustrates an example of a keg 10 in an empty state, with aframe having legs, showing the telescoping feature of the legs,according to an aspect. The telescoping legs 129 may be used forcollapsing or folding the keg 10 such that the keg may be shipped orstored in a flat state, in an accordion box or flat packed in a foldingbox.

FIG. 42A illustrates a motor 79 and motor shaft that may be associatedwith the auger screw conveyer shaft or paddle shaft, according to anaspect. Motors may be connected to shafts or fixtures that they are todrive by hard connections. These type of connections may not be quickrelease or quick engage. Some other types of motors may be connected toa clutch, which may wear down after prolonged usage. The coupling may bemade with a friction shaft fin 134 (“fin” or “fin pin”). The frictionmotor to shaft coupling may be a pin-fin friction coupling wherein thedriving fin shaft may either slide into two pins on the end of the augeror paddle shaft, or the opposite may occur where the driving shaft mayhave two pins. The top of the fin 134 may be beveled to a pointed ortriangular tip, as shown. An advantage of the beveled tips of the finand pin may be that the fin and pin are prevented from butting together.If this occurs, then friction coupling cannot be completed. The motordriving shaft and the work-utility shaft may be free-wheeling, able tomove and rotate to the side, which may allow the wedges to drive pasteach other to create a friction coupling. Another advantage may be thatthe container of food or drink in the keg 10 may be quick-change, andeasily removed by the user so that it may be replaced with a new one.Another advantage may be that the inclusion of paddles within the kegitself may reduce mess and the need for cleaning, as a beverage or foodmay no longer need to be transferred into a separately container thathas paddles.

FIGS. 42B-42D illustrate a side top perspective view, a top perspectiveview, and a top plan view, respectively, of an example of a motorcoupling 135-a having a ridged cylinder design, according to an aspect.

FIG. 42E illustrates a side perspective view of a motor coupling havinga rough surface funnel design, according to an aspect. The motor 79 maythrough the coupling 135-b drive the auger silo 110.

FIG. 42F illustrates a side perspective view of a motor coupling havingteeth on the surface for gripping, according to an aspect. The coupling,powered by a motor 79, may drive a paddle shaft 30 a.

FIG. 43A illustrates a detailed partial side view of the keg 10 of FIG.35C, which may include an alternative example of a top opening andfriction coupling 215, according to an aspect.

FIG. 43B illustrates a detailed partial side view of the keg 10 as shownin FIG. 43A, with a motor 79 and upper auger 110-a coupling associatedwith the auger 110, according to an aspect. The motor 79 may beassociated with a fin pin 134, which may connect with an upper auger110-a. The upper auger 110-a may be the driving auger, and may drive theauger 110. The friction coupling may be a vertical slot and may becylindrical, with a sleeve where the top fin-pump male friction couplingglides into the sleeve slot 154 of the keg 10, similar to a malecoupling into a female coupling. The wide opening of the fin malevertical coupling may be needed to allow the auger screw conveyer 110 tomove in and out of the keg and connect to the lifting auger screwconveyor, and may also allow the driving auger to connect to the liftingauger in the keg.

FIGS. 44A-44B illustrate a box 131, with the top unfolded and partiallyfolded, respectively, constructed of bio-cardboard that may make up theouter shell 131 of a keg, which may have a bio-plastic bag orbio-plastic bottle inside (shown only in FIG. 44B for clarity),according to an aspect. The bio-cardboard keg may be printed witheco-friendly ink and eco-friendly glue or tape strips. Where adhesive ispre-applied to the box flaps or folds, as shown by 131-a and 131-b, aprotective film may be placed over it and removed when the adhesive isneeded. The protective film may be biodegradable. An advantage of thebox may be that the beverage contained inside may be protected from UVsunlight. An advantage of the adhesive may be that boxes may beflat-packed for storage or shipping and later easily assembled. Anadvantage of having overlapping strips of adhesive 131-a and 131-b maybe that the strength of the box is increased. The boxes may beconstructed such that a user may assemble the boxes when needed, and maybe folded along seams and glued or taped together with pre-applied glueor tape strips, for example. The folds of the box may overlap such thatthe strength of the box is increased. The box may include telescopinglegs (as shown by 129-a in FIGS. 41B-41C) that allow for the box to becollapsed flat, and then re-assembled by the user. An advantage may bethat a separate tape dispenser and/or knife for tape is not needed bythe user.

FIG. 45A illustrates a partial sectional side view of a keg 10 connectedto a beverage dispenser by a flexible bio-plastic or rubber hose/tube107, according to an aspect. The bio-plastic friction coupling of thehose/tube 107 on the keg 10 may be pushed on or pulled off.

FIG. 45B illustrates a bio-plastic elbow 130, which may be flexible,which may be used where space is limited in the beverage dispenser,connecting a dispenser 50 with a keg 10, according to an aspect. Anadvantage may be that the elbow allows flow of liquids where a hose/tube107 may restrict liquid flow if bent at an angle. The keg 10 may includea straight twist lock coupling as part of the pump housing or as part ofthe keg pour spout opening.

FIG. 45C illustrates a partial side view of a hose 107 that may beattached to a screw-on cap 11, according to an aspect. The hose 107 mayallow for both horizontal and vertical product flow.

FIG. 45D illustrates a partial side view of an elbow 130-a that may beused for connecting a dispenser 50 with a keg 10, according to anaspect. A fixed vertical elbow piece 130-b may allow for verticalproduct flow, and a bent elbow 130-a may be used for horizontal andvertical product flow between a dispenser 50 and a keg 10. Individualpieces used for connecting a dispenser 50 with a keg 10 may snaptogether and lock, for example, or may be connected by any othersuitable means.

FIG. 46A illustrates a side view of a bottle 127 fitted with abio-plastic pour spout with a manually operated nozzle 138 having a gatevalve 108, according to an aspect. The pour spout may be connected to abio-plastic or bio-rubber hose 107 which may be connected to a screw onmale V-friction coupling which may be received by a corresponding femaleV-friction coupling. The male coupling may include a petcock valve 102.This gate valve 108 pour spout 138 with gate valve 108 may be used withany keg whether the keg operates by gravity flow or self-propulsion. Akeg or water bottle may also use a bio-plastic bladder bag liner(“bladder bag,” “bladder bag liner,” “balloon bladder,” or “bladderliner”) 133 inside of the keg or water bottle, to create aself-propulsion system. The keg or bottle using a rubber balloonself-propulsion system may be capable of holding ½ gallon to 10 gallons,for example, and or may be shaped and sized like small bottle and becapable of holding 12 ounces to 24 ounces, for example. The bio-plasticpour spout may be used with any existing bottle or container in standardmarket packaging.

FIG. 46B illustrates a bottle 127 with a bio-plastic screw-on top thatmay be used with a bottle 127 for storing or shipping, according to anaspect. The bottle may include a petcock valve, and may include a rubberballoon bag 133 for self-propulsion.

FIG. 46C illustrates an airtight seal such as a male friction couplingpour spout, which may be V-shaped or cylindrical, having a gate valve,which may include a petcock valve 102, and finger pull tabs 127-a forpulling over a spout, according to an aspect. The hose may include abio-plastic ribbed surface, such as, for example, ribbed ridges, toaccommodate a tight connection of the hose to the fitting, and may bepulled over another container, such as, for example, the opening andthreads of a bottle neck, and may be used, for example, with anyexisting bottle such as for soda, water, beer, wine, and so on.

FIG. 46D illustrates an airtight seal bottle cap and pour spout 136 thatmay be used with any existing bottle, such as, for example, a wine,champagne, or water bottle, according to an aspect. The bottle cap pourspout 136 may include a gate valve 108 and a lever 137 for manualoperation of the spout. The pour spout 136 may also include finger pulltabs 127-a.

FIGS. 47A-47C illustrate a side view of a female V-shaped or cylindricalfriction coupling adapter 97-a, a detailed view, and a side view,respectively, of the adapter 97-a inside of a bottle 127, according toan aspect. The female V-shaped or cylindrical friction coupling adapter97-a may accommodate any size beverage container opening, such as, forexample, a milk carton, 2 liter soda bottle, juice bottle, and so on.The hard V-shape coupling 15 may have a well tube 22-a attached to it,which may be telescopic. The female V-friction coupling 15 funnel mayhave a rubber boot or stretchable expansion membrane 126 that maystretch over the top of the neck of a container (shown as 127 in FIG.47C), fitting snugly over the neck and giving a perfect seal. Anadvantage may be that the existing shape of bottles may not need to bealtered and existing bottles may be able to use this coupling. Bottlersmay, at the time of packaging, insert the adapter 97-a after filling thebottle, or users may insert it after removing a storage cap. This mayallow users to use any existing packaging inside of the dispenser, byallowing the male V-friction coupling that is a part of the pump lead orpour spout housing to connect to existing bottles or other packaging viathe female V-friction coupling. The adapter 97-a may also be a permanentpart of bottle packaging. The adapter 97-a may, on the expansionmembrane 126, include finger pull tabs 127-a which may aid in puttingthe adapter on a bottle, or pulling it off a bottle. An adapter with astretchable expansion membrane 126 may also be used with, for example,aluminum cans and may assist in the opening of the cans, and thestretchable expansion membrane 126 may be used to keep a beverageairtight. As an example, a carbonated beverage may be covered using anexpansion membrane 126 thus reducing the carbonation loss in thebeverage.

FIG. 47B illustrates another example of a telescopic well tube of theadapter 97-a. The telescoping friction sleeve 22-a may slide to extendor retract and may be held in place by side-to-side friction. Thetelescopic well tube 22-a may include friction ridges 22-b along thesides, which may be flexible, and may assist in holding the well tube22-a in position at a desired length. The friction ridges 22-b may alsobe used with a friction fin 22-c, for example, or may be used without afriction fin. A friction fin 22-c may be used as a larger flexiblestopper for holding the well tube 22-a in place.

FIG. 47C illustrates a standard bottle 127 with its cap removed. Theexpansion membrane 126 of the adapter 97-a may allow any existingcontainer to be adapted to use the V-shaped coupling. An existing bottle127 may be placed into the dispenser, and the female adapter may be usedwith the coordinating male V- or cylindrical-shaped friction coupling ofthe dispenser. Again, the well tube 22-a of the adapter 97-a may includefriction ridges 22-b which may assist in holding the well tube at adesired position.

FIG. 47D illustrates a side view of a bottle 127 with a bio-plasticbladder bag liner 133 having an expansion membrane top 126, similar tothe adapter 97-a of FIG. 47A, such that the opening of the bio-plasticbag liner 133 may be able to stretch over the top of any size container127, such as a bottle, growler, and so on, according to an aspect. Thebio-plastic bag 133 may be thermally protective such that it maywithstand temperatures below the freezing point of water and above theboiling point of water. A balloon bladder 133 may be stretched over topof a plastic bottle, with a snap or screw on cap placed on top, with abio-rubber nipple in the top. The balloon bladder 133 may be used with,for example, a baby bottle, which may also be used with a double cap,having a top cap and a bottom cap. The bottom cap may have a femaleV-friction coupling, and the top cap may have a male V-friction couplingthat may go into the female V-friction coupling when the top cap isscrewed or snapped on over the bottom cap. The female cap may havefriction tabs, which may be nipples that the balloon bladder top openingcan stretch over. The nipple may create a friction hold and air barrier.The friction nipples may be around the bottom and sides of the coupling.A removable baby bottle nipple may go onto the top cap. A rubber flangemay stop the nipple from pulling off into the baby's mouth, which mayprevent choking.

FIG. 47E illustrates the side view of the bottle 127 with a bio-plasticbladder bag liner 133 having an expansion membrane top 126 of FIG. 47D,also having a storage unit 155 for holding extra bladder bag liners 133,according to an aspect. The storage unit 155 may be screwed on to thebottle 127 by threads 166 or attached by any other suitable means, andmay hold extra bladder bag liners 133 such that the user may be able tokeep extras with the container or bottle 127 and may not need to searchfor them.

It should be understood that any container that may use a bio-plasticbladder bag or rubber balloon bladder may also include a magazine orholder for spare bags, which may be attached to the container by anysuitable means. The user may store extra bags in this magazine orholder, such that they can easily find replacement bags.

FIGS. 48A-48C illustrate a bladder liner in various states of beingstretched, which may be used inside of a water bottle or keg of any sizesuch as ½ gallon to 10 gallons, according to an aspect. Personal waterbottles having a narrow neck may be difficult to clean. An advantage ofa bladder liner 133-a may be that the liner may be disposable, such thatwater scum or bacteria does not accumulate inside of the bottle. Theballoon liner may be made of bio-plastic material, and may be stretchedover the top of the container. The flexibility may allow one type ofliner to be used for a variety of sizes of containers or bottles and mayalso allow for self-propulsion in personal bottles. The balloon linermay also expand when being filled with a beverage, such that theelasticity of the liner may help to self-propel a beverage out when auser takes a drink. As an example, the self-propelling may be used forindividuals with mobility issues, or athletes in competitive situationswho are not able to tilt their head back to drink.

FIGS. 48D-48E illustrate side views of examples of a bladder liner 133-bhaving a V-shaped neck 133-c, according to an aspect. The V-shaped neck133-c may aid in fitting the bladder liner or rubber balloon into anytype of container for allowing the container to self-propel itscontents.

FIG. 48F illustrates a keg 10 having an air pump 120 and rubber balloonbladder 133, according to an aspect. The air pump 120 may be used topump air into the space within the keg to propel liquid or food out ofthe flexible bladder 133. It should be understood that any keg may beconstructed to be able to use a balloon bladder 103 to hold liquid orfood, such that the balloon bladder 133 may be replaceable with a newbladder at any time.

FIGS. 49A-49B illustrate side views of a cylindrical friction coupling,having a male coupling 215-a and female coupling 215 in a coupled stateand uncoupled state, respectively, that may be used with a keg,according to an aspect. In order to assist in an airtight seal, the malecylindrical coupling 215-a may be inserted into the female cylindricalcoupling 215 and also may slide into a channel sleeve 167 that is deeperinside of the female cylindrical coupling 215. The channel sleeve 167may be even with the leading edge of the female cylindrical coupling215. An advantage may be that the cylindrical coupling may be moreadaptive to the operation of the petcock valve and auger shaft, whichmay allow for better control of soft serve food, for example. Thecoupling may also be a rounded bull nose type coupling, as shown by215-b, which may be in a U-shape, for better airtightness.

The cylindrical coupling may include metal plates where a metal-to-metalseal may take place, between a stainless steel male cylindrical couplingand a female stainless steel cylindrical coupling. The components mayalso be constructed from polymer plastic materials, for example, and mayhave flexible semi-plastic rubber seals where the male and femalecomponents meet.

FIG. 49C illustrates a side view of another example of cylindricalfriction coupling with a female friction coupling 215 and acorresponding male friction coupling 215-a in an uncoupled state thatmay be used with a keg 10, according to an aspect. The coupling may forexample snap and lock into place into a receiving channel. Snap pins215-d may fit into snap pin cavities 215-e. Flexible rubber washerswhich may be constructed from rubber, for example, may be placed at thetop of the channel to create an airtight barrier. Pins may also be usedor a sleeve in the channel to create airtightness.

FIG. 49D illustrates a cylindrical coupling having a female frictioncoupling 215 and a corresponding male friction coupling 215-a, withfriction plates 170 that may be used with a keg 10, according to anaspect. With the use of the friction plates 170, the male coupling maynot need to go into the female coupling, and instead, a seal may beprovided by weight and friction. As another example, instead of a sealtaking place with the sides of the male and female couplings, theairtight seal may be caused by a side shaft gasket plate on the malecoupling and a bottom rubber seal or gasket at the end of the malecoupling adjacent to a female flat plate. The friction plates 170 may besandwiched between other elements in order to ensure a tighter seal,such as, for example, a gasket 169, a rubber seal 168, or any othersuitable means for an airtight seal. The two friction plates 170 may bepressed together by weight, and the gasket 169 and rubber seal 168 maybe flexible. The presence of the friction plates 170 may also allow forthe channel of the female coupling 215 to be smaller.

FIG. 49E illustrates a detailed view of the cylindrical coupling of FIG.49D showing friction plates with a gasket 169, according to an aspect.The gasket 169 may allow for a tighter seal of the coupling. The bottomseal created by the friction plate 170 is also shown, and the rubberseal 168 at the top of the channel.

FIG. 49F illustrates a detailed view of the cylindrical coupling ofFIGS. 49A-49B having a female bull nose or dolphin nose coupling 215-cand a corresponding male bull nose or dolphin nose coupling 215-b. Thebull nose or dolphin nose shape may allow for better guiding of the malefriction coupling 215-b while entering the female bull nose or dolphinnose friction coupling 215-c. The rounded U-shape of the bull nose ordolphin nose may have more surface area at the point than a V-shapedpoint, which may allow for a better and tighter seal. The better andtighter seal by a bull nose or dolphin nose may also prevent liquidsfrom spilling out around the point of contact. An advantage may be thatthe airtightness may extend the shelf life of liquids or foods containedwithin the keg. Another advantage may be that a bull nose type couplingis universal and may be used with many different types of kegs orcontainers, and may allow the user of an auger conveyer within thecontainer for a more even flow of the liquid or food inside.

FIG. 50 illustrates a multi-use keg 10-a that may include multiple pods(“pods” or “chambers”) 404-a-404-d, according to an aspect. As shown asan example, one multi-use keg 10-a may, as an example, include four pods404-a-404-d. A pod 404-a may include a chamber 402 having a petcock gatevalve 102 (shown only in pod 404-a for visual clarity), and may includetwo petcock valves 102, which may be automatically opened by, forexample, a stepper motor and may regulate flow of the keg contents. Thegate valve may allow added flavor ingredients to flow from the mainreservoir of the keg 10-a into a second reservoir chamber for mixing,which may be, as an example ½ ounce to 2 ounces in capacity. The gatevalve may include a fin 102-a, which may jut out as a plate, and may beat a 90 degree angle to the gate valve 102, and may perform the actionof a handle at the end of the petcock valve.

Each pod 404-a-404-d may also include an auger to assist in keepingproduct thoroughly mixed, as shown in FIG. 35C. An auger may be omittedfor liquids, or may be included when using a keg 10-a for thicker foods.

The keg 10-a may include at least a scannable tag 172 for reading orproviding data or information about the contents of the keg 10-a. Thescannable tag 172 may be similar to the scannable bar code (shown by 89in FIG. 22), and may, for example, be tags such as bar codes, QR codes,radio-frequency identification (RFID) near field communication (NFC),and any other similar machine-readable data. The scannable tag 172 maytherefore be able to provide information about the contents of eachchamber 404-a to a dispenser, for example, such as, for example,ingredients, the amount of sugar, recipes including the contents of thechamber, volume of each ingredient, and so on. The information containedin the scannable tag may be read by a scanner on a dispenser of the foodor beverage (such as, for example, a scanner shown by 90 in FIG. 22).

The keg 10-a may include at least a scanner 172 for reading bar codes,QR codes, radio-frequency identification (RFID) near field communication(NFC), and any other similar machine-readable data. The scanner 172 maytherefore be able to read information about the contents of each chamber404-a, such as, for example, ingredients, the amount of sugar, recipesincluding the contents of the chamber, volume of each ingredient, and soon.

It should be understood that any of the materials used for constructingthe keg may be biodegradable, such as, for example, bio-plastic that maybe recycled by single-stream recycling processes.

It should be understood that a friction coupling in any of the aboveexamples may be V-shaped or cylindrical, the male and female couplingscorresponding with one another.
